At GDExperts Ltd, I lead backend engineering and solution architecture for enterprise telecommunications platforms and integration services in the MTN Uganda environment. I translate business, integration, and regulatory requirements into secure, maintainable backend solutions.

Previously at GDExperts Ltd, I led the real-time integration between MTN Uganda systems and Uganda Revenue Authority's EFRIS platform. I also introduced automated testing that reduced manual testing by 60% and regression testing time by 50%.

At Vortex Lab Ltd, I design end-to-end solution architectures across application, integration, data, and infrastructure layers. At The Medical Concierge Group | Rocket Health Uganda, I led an automated end-to-end testing framework covering more than 75% of critical healthcare scenarios.

Earlier, at Bodastage Solutions, I led the architecture, backend development, and delivery of Project THEAServer, a regional East African haulage-tracking platform. At Yo Uganda Limited, I delivered digital solutions including NSSF GO USSD and Friends With Benefits, contributing to an 18% increase in customer interactions.
